Giving back has to do with the way I was brought up and the fact that I've traveled widely and seen terrible situations in the world. To sleep well at night, those of us who are in a position to help must address these situations. I'd get far greater satisfaction out of, say, walking into a hospital I'd built in South Africa than I would by sitting on a beach. I'm fortunate enough to be in a position to make a difference, and I don't want to waste that. I suspect I was also lucky to have parents who drove me from a young age.

Perhaps, therefore, it is odd that if there is any one phrase that is guaranteed to set me off it's when someone says to me, 'OK, fine. You're the boss!' What irks me is that in 90% of such instances what that person is really saying is, 'OK, then, I don't agree with you, but I'll roll over and do it because you're telling me to. But if it doesn't work out I'll be the first to remind everyone that it wasn't my idea.'

The balloons only have one life and the only way of finding out whether they work is to attempt to fly around the world.

Don't think what's the cheapest way to do it or what's the fastest way to do it. Think what's the most amazing way to do it.

A generation ago, the image was that you had to trample everyone else down to succeed; but I don't believe that makes good business sense.

Mentorship is key to unlocking each of our entrepreneurial spirits.

Allowing my people to have a good work-life balance by working flexibly is very important to me.
